<u>Answer</u>:
<em>Sodium potassium pump works by following several steps.
</em>
<u>Explanation</u>:
<em>1. Carrier protein binds three molecules of Na+
</em>
<em>2. ATP is split, phosphate bonds to carrier.
</em>
<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell.
</em>
<em>4. Carrier binds two molecules of K
</em>
<em>5. Phosphate is released.
</em>
<em>6. Potassium is released inside the cell
</em>
Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.
It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.
<em>Thus it is an active transport mechanism.
</em>
Glycolysis evolved very early in ancestors that are common to all the domains of life.
This is because the site of glycolysis is cytoplasm which is present in both prokaryotes as well as eukaryotes.
As prokaryotes are the early ancestors of all domains of life therefore it is also considered that glycolysis is evolved very early.
Answer:
d. raise the apparent value of the equilibrium constant, L.
Explanation:
Allosteric regulation is a type of regulation of an enzyme by binding an effector molecule at a site other than the protein's active site (i.e., the allosteric site). The equilibrium constant (L) refers to the transition between two forms of an allosteric protein in absence of a ligand. The properties of allosteric enzymes are explained by conformational changes associated with a low-affinity tense (T) state, or a high-affinity relaxed (R) state. Negative allosteric effectors are molecules that bind to the allosteric site on an enzyme in order to decrease its activity, thereby leading the enzyme to a low activity T state and thus increasing the value of the equilibrium constant.
